"Bumrah is not out of the World Cup yet," Ganguly told the Xtra Time digital channel in Kolkata on Friday. The BCCI president added that he was keeping his "fingers crossed" and that a final decision could be taken in the "next two or three days".

Ganguly's comments come on the back of a BCCI media release earlier in the day which said Bumrah had "sustained" a back injury and was being monitored by their medical team at the NCA.

While the BCCI has not put out any further detail on the nature of the injury, ESPNcricinfo has learned that Bumrah went for a scan on his back in Thiruvananthapuram on Wednesday. It is learned that those scans revealed a stress-related injury in his back. Keeping in mind Bumrah had only recently recovered from a back injury which had kept him out of the Asia Cup, the Indian team's medical staff, together with the NCA, decided to have fresh scans done in Bengaluru.

The fresh scans, which were taken on Thursday, will be studied by independent medical consultants hired by the BCCI who will then coordinate with the board's medical staff to determine the next step.
